"Rescued kidnapping victim Elizabeth Smart said Wednesday she understands why some human trafficking victims don't run."

"Smart said she 'felt so dirty and so filthy' after she was raped by her captor, and she understands why someone wouldn't run 'because of that alone.'"

Remarks made at a Johns Hopkins event that predated the story of the escape of the Cleveland victims.

"I thought, 'Oh, my gosh, I'm that chewed up piece of gum, nobody re-chews a piece of gum, you throw it away.' And that's how easy it is to feel like you know longer have worth, you know longer have value," Smart said. "Why would it even be worth screaming out? Why would it even make a difference if you are rescued? Your life still has no value."
